This moves and isolates the tar code to tar.c. And the actual
file extraction to disk is moved to extract.c.
A new API is introduced and used for v2 file extraction. This
essentially moves and isolates the apk_sign_ctx_* beast into
extract_v2.c and offers a saner interface to handling packages.
A place holder is added for v3 extraction.
The new v3 applets don't use it, and eventually all applets will
use the new formats only.
This prepares the code for this, and moves trust, id_cache, and
root_fd to apk_ctx which is enough for v3 applets at this time.
The generic code is made to not initialize apk_database if it's
not needed.
This uses some macro trickery to make sure that there's one-to-one
mapping with the option index enum and the descriptor. The down
side is that enum's are generated via #define's and editors might
not pick them up for auto completion, but the benefits are more:
it's no longer possible have mismatching enum value and descriptor
index, and the amount of source code lines is less.
This reduces the number of relocations on PIE binaries, and also
reduces the executable size. Parsing of the options is slightly
sped up as only the exact matching option group parser is called.
This creates main help like:
--
usage: apk [<OPTIONS>...] COMMAND [<ARGUMENTS>...]

This apk has coffee making abilities.

And applet specific help like:
--
usage: apk add [<OPTIONS>...] PACKAGES...
Description:
apk add adds the requested packages to WORLD and installs (or upgrades)
them if not already present, ensuring all dependencies are met.
Options:
--initdb Initialize a new package database
-l, --latest Disables normal heuristics for choosing which repository to install a
-u, --upgrade When adding packages which are already installed, upgrade them rather
-t, --virtual NAME
Instead of adding the specified packages to WORLD, create a new
--no-chown Do not change file owner or group
